'HINGELD DRYING FRAME.

- Application filed. July 14,

- This invention relates to drying forms and more particularly tostocking drying forms ofthe type disclosed in my prior Patents #875,135,granted December 31,1907, and '5 1393,29 1, granted May 6,1924, and hasfor one of its objects to provide a device of this character which willbe simple in construction, comparatively inexpensive to manufacture andmore efficient in, use'than those here'- tofore proposed.

A further object of the invention is to prov vide an improved hingeconstruction for such.

a drying form which may be lnexpensively manufactured and assembled andwhich will provide a frictional pivotal connection for the main elementsof the form which will effectively hold them in any desired relativepositions. I

A still further object of the invention is to provide a hingeconstruction for a. drying form of the classdescribed'inwhich the partsare frictionally connected to'm aintain them in set angular positionswhile at-thesame time they are positively held against relative axial orlongitudinal movement so that the hinge will not become disconnected.With the above and-other objects in view which will appear as thedescription proceeds, the invention consists in the novel details ofconstruction and combinations and arrange ments of parts more fullyhereinafter disclosed and particularly pointed out-in the appendedclaims. 7 V j Referring to the accompanying drawings forming a part ofthis specification inwhich like reference charactersdesignate like partsin all the views:

Figure 1 is a perspective viewof the top portion of a drying form of thegeneral type shown in my said prior patents, showing one example of theimproved hinge construction;

Fig. 2 is a top plan view of the parts shown in Fig. 1, a portion of thehinge element being broken away;

approximately on the plane indicated by the line 33 of Fig.2;

Fig. 4 is a fragmentary plan View of* a somewhat modified form of theinvention;

Fig. 6 is a fragmentary perspective view of a stillfurthermodified formof the invention.

Fig. 3 is a transverse sectional view taken- Fig. 5 is a transversesectional View of the form shown in Fig. 4,1taken approximately 1926.Serial no. 122,37s.

Referring more particularly to Figs. 1, 2 i V and 3 of the saiddrawings, the formcomprises a pair of frames, Sand-6, of loopconstruction, (only the upper portions of. such frames being shown-inFig. 1,) which frames are preferably formed of wire, and of the samegeneral character as those set forth in my said'prior patents. The upperends of the wires constituting the said frames are turned inwardlytoward one another to provideinturned end portions 7 and 8, respectivelyforming transverse members of the frames, and whichend portionsconstitute .each' one element .of a hinge; The other element" isformedof a'sheet of metal 9, the opposite sides of which are rolled orstamped to pro vide' substantially cylindrical loops .10 and.

11 which receive the inturned ends 7 and 8 of the frame members 5 and 6,respectively.

The inturned ends 7 and 8 are provided respectivelywith grooves 12 and13, see Figs. 2 and ,3,'e:-rtendmg around their peripheries intermediate their extreme ends and the bend which joinsthem to the mainbody portions of the frames, and the inneredges'ofthe cylindrical orloop members 10, and 11 are formed during the stamping operation withindentations or keys 14 and 15 respectivelv, which are forcedinto thegrooves 12 and 13 respectively, thereby effectively retaining theinturned end'portions 7 and 8 against axial movement, while at the sametime permitting of relative rotary movement. The indenta tions or keysare preferably of such dimensions as to frictionally engage the bottomorsidewalls, or both, of the grooves 12 and 13 with sufficient force tohold the, frame members 5 and Gin any desired adjusted positiOns;

The hinge member 9, is preferablyofsuch dimensions that it will maintainthe upper ofthev invention shown in Figs. 1 and 5, it

will be noted that substantially the same re sults are here accomplishedin a somewhat different manner. That is to say, instead of providing theinturned end portions 7 and 8 upon the frame members 5 and 6 withgrooves which receivekeys or projections carried by the hinge member 9'the construction is reversed inthat theend portions 7 and 8 areprovidedwith'projections inithe form of bi'ghts or'reverse bends 16andl'z whichare loopportions 10 and 11 of the hinge member 9, as will bereadily understood. These bights or reverse bends 16 and 17 frictionallyengage the 31 de walls of the notches or recesses 18 and 19 and serve tohold the frame members 5 and 6 1n *ar1ous set angular positions while atthe same tnnethey' will prevent the end portions 7 and 8 from movingaxially and being withdrawn from the loops 10 and 11. I The form of theinvention shown in Fig. 6

' is closely analogous to that shown inFigs.

4 and 5 except that instead of providing the reverse bends or bightssuch as 16 and 17, the end portions 7 and 8 are made somewhat shorterand the extreme ends 20 thereof are turned outwardly through the notchesor recesses18and 19.

in these two latter forms of the invention the edges 21 of the notchesor recesses 18 and 19 serve as stopsto limit the angular move ment'otthe frame members 5 and 6 in that the said edges would be engaged by thepro+ jections formed by either the bights 16 and 17 or the outturnedends 20, when the said frame members are opened at an angle tosubstantially 180. Of course, the angle of such opening may be readilycontrolled by changing the location of the edges 21 or in other Words bymaking the said notches or recesses 18 and 19 deeper or shallower ascircumstances may require; 7

It will thus be seen that this invention provides a hinge constructiontor-drying forms and the like which may be inexpensively manufacturedand which -will efiectively serve to trictionally hold the form membersin any adjusted angular position while at the same time holding theirinturned end pork details ofconstrnction as well as the recise Iarrangement of parts, without departing from the spirit of the inventionand th refore, it is not Wished to be limited tothe above disclosureexcept as may be required by the claims.

'l/Vhatis claimedis: a I y 1.
